As many as six species are included inthe British list, all of which are esteemed for food. A very C 2 2o MARINE AND FRESHWATER FISHES remarkable structural feature in the Gurnards is connected,with the peculiar modification of the pectoral fins, certain,usually three, of the rays of which are detached from theothers, separately movable, and so constituted that theyform ambulatory organs, wherewith these fish are in thehabit of literally walking along the bottom of thesea.
